Tool Vevor Drill Bit Sharpener Improved

[DavidR8]

My parts were printed on a printer that had not been calibrated, and I'm finding the 28mm bores wont accept the chucks without chamfering and sanding.

@DavidR8 can you let me know if this is an issue when you visit @YotaBota please

My 8mm threads formed very well, and I ran them thru with one of my many 8mm taps. The tool insert block snapped right into the block holder...

Assume I can just measure with inside mic?

Yes that should work just as well.

The width was verified against a number of different chucks to it has to be just the printing of my part. Sadly I dont have any inside mics and I dont know where my brother keeps his so even if I ran to his place I'd be out of luck

seems to want to print under-sized but is 28mm in the model for the A tool insert. The B tool block I forgot to change it from 27.94mm to 28...

I'll change the models to be 28.1 and see what that does for it.

Heads up that the 5mm inserts I have are 6mm in diameter and 10mm long so not a good fit in the bores.

want me to send you a new stl file with smaller deeper holes? I hate that there isn't a standard.

A new file would be great

Here is the file

Here is the file

@DavidR8 that means the duo motor mount wont work either because that has bigger insert hole.

A new file is here if you want it

 

[DavidR8]

Thanks I'll print those two new prints tonight.

 

[DavidR8]

That’s better.

So I noticed another issue. The motor boss wont fit into the motor mount. It is printing smaller than the actual model. I made the tolerances too tight. I had to sand mine which is frikken annoying. I'm making new stl file with slightly larger opening..

Duo Motor Mount Rev2

I got my parts ready to install, but now I wont get to them tomorrow because I didn't get my amazon order in on time. My wife came home in a panic because she spotted a stray dog and made me go out and hunt it down. Then it had no collar so I had to run it to my vet before they closed.

Thank god the dog was chipped... because the last thing I need is a golden doodle the size of a horse.

Temporary solution to hold the block in place for a photo using two 8mm taps.

Well crap. I’m half way through printing that piece

sorry, I wish I'd have noted it earlier, but I was in the middle of that when the lost dog episode played out...

The part is not wasted you just need to sand a bit... which I hate
